Microwave tunnel conveyor line is a kind of mechanical equipment which is driven by friction to transport materials in a continuous can not only finish the transport of broken materials, but also can be made into the transport of complete goods.

The purpose of this study is to simulate the water spray suppression of conveyor belt fires in a largescale tunnel with ventilation. The flame spread over the conveyor belt was modeled to reflect the real development of the belt fire. The CFD model was calibrated using largescale experimental results.

A tunnel boring machine (TBM) also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through hard rock, sand, and almost anything in between. Tunnel diameters can range from a metre (done with microTBMs) to almost 16 metres to date.

Nov 15, 2018· CFD simulation to investigate the flow and temperature behaviour of the air in the ventilation supply of buildings,,, and of conveyor belts to be airconditioned is an established method. Consequently, CFD simulations are carried out to investigate the fluid mechanical behaviour of the air, the heating behaviour of the chocolate bars and to validate the data measured in the laboratory tests.

Road Tunnel Ventilation. In road tunnels ventilation rates are needed to dilute the pollutant emissions from vehicles like Carbon Monoxide (CO), Nitrogen Oxides (NOx) and soot (particles matter) in order to keep acceptable air quality for the users. Just as important is controlling the effects of a fire in tunnels.
